CLOSING DEVICE AND SAFETY SEAL.

Application filed January 30, 1925, Serial No. 5,881, and in Mexico December 30, 1924.

My invention refers to a new and useful seal or unbreakable and safetyseal, or more particularly to means for insuring the safe closing of railroad freight cars, baggage cars, money bags, refrigerating cars, water meters or electric meters, and in general every place where ,a safety seal is desired, as once this seal is closed it can not be opened again without destroying or cutting theribbon or strap attached to the seal.

Such results are obtained by means of the mechanism illustrated in the drawings herewith attached, reference'to which is made as follows I Fig. 1 is a perspective view, partly broken away, of the seal prior to the assembling thereof.

Fig. 2 is a longitudinal showing the complete device as applied to use.

Fig. 3 is a perspective view of the complete seal. a

Fig. 4 is a partial perspective View of the internal 'inechanisn'i of the seal removed.

V Fig. 5 is a perspective view of-the sliding piece of the internal mechanisnrof the parts.

Fig. 6 is a detail of the split rings forming part of the device, one of which is shown in section.

Fig. 7 is a perspective view of a further part of the internal mechanism of the seal.

Similar reference numbers makereference to the same parts or pieces in the different figures. Y

v The container or case of the seal (Fig. 1) is formed by the cup 11, which can either have a cylindrical form or any other desired shape that can be stamped. That is formed by one piece provided with a slot 12in its curved face, for the admission of the extremity of ribbon or handle, another slot 13 in its bottom for the passage of the handle and a flange 14 disposed in the upper section of the cup, perpendicular to its base, which can be used as a lead for the internal mechanism, to maintain and place the same in position; said cup being provided in its upper edge with two flange sections 15 tojoin the cover on the cup. This cover 16 is slightly curved and is attached in part to the cup, which is bent to cover the same, after which the cover 16 is attached in a point diametrically opposed by means of the buckle 17 provided with the slot r 18, which slot coincides with the slot 12 on 1 the cup, and said buckle attached by means sectional View of the ribbon or strap 19, constitutes the handle of the seal, said strap being provided with a perforation 20 in one of its extremities for the purpose of anchoring this end of the handle in the closing mechanism by means of the hoops or rings that are hooked in said perforation thus eifectingtheclosing operation. The different parts of the cup, cover, buckle and handle constitute one single piece in itself, of any metallic material or any other suitable for the purpose.

The interior mechanism is lodged in the inside of the cup 1, and constitutes four pieces; one crown or pedestal 21, (Fig. 7)

formed by a flattened tubular sectionor a double section, of the form and structure shownin the drawing,provided with angular grooves 22, the horizontal end of the groove being the one that servesas slidable groove for the hoops or rings, and the invterior sides, which constitute the, guides of the said rings; the said part being of a wider opening in its. inferior part and in its superior part leaving justa space sufliciently wide for the sliding ofthe piece that will be later described. centre it is formed with a semi-circular cut 23, which cut engages the flange 14 on the cup thus keeping't-he mechanism in position.

The slidable piece 24 (Fig. 5) is formed a with double walls joined along their lo.wer

part with folded portions 25 at right anglefor the sake of safety and resistance, and provided with a hole in its centre as at 26. This piece 24 is inserted in the crown or pedestal 21, and receives the end of the strap or handle 19 that is introduced 'inthe interior of said piece 24 between its walls. The hole 26 coincideswiththe perforation 20 of the ribbon when introducing the end of the handle or strap in the slidable piece 24. Two hoops or rings 27, opened at one point are disposed in the slots 22 of the pedestal 21, introducing said rings through the horizontal end of the slots, one on each side, and keeping the same in position on the other ends of the said slots, which constitute the guide of the rings. The extremities of each of the rings are set on the plate of the slidable piece 24, underneath the perforation, in such a way that when pushing the piece 24, through the action of the end of the strap or handle 19, said perforation 20 coincides with the perforation 26, the ends of the rings close within the perforations', thus effecting the closing of the 80 In its lower end and in the j til? handle through the action of the rings, w are thus joined in the perforations or the handle 19 and slidable piece The closing mechanism thus formed by the four piec s consisting of: pedestal or crown :21, 7) slidable piece 24;, (Fig. 5) and the the rings 27 (Fig. 6) the mechanism of which is disposed in the interior of the cup 11, the same being set in the manner represented in F i g. 4, and in the cross section on Fig. The cover is is bent over the cup or c so 11, covering its entrance and is fixed by means oi the flanges 15, which fasten over the cover. The buckle 17, is also folded in the interior of the cup, thus forming a double wall and coin c-iding the groove lo witi, the groove 12 on the cup, for which purpos the strap or handle 19 that should prelferably be of a flexible material will go through the lower groove -3 on the base of the cu p, such as described in F 2, and when out of same will form a free handle to be inserted in the place to be shut. Once in place the end will be intro-- duced through the groove 12 ot the cup to go into the internal ineclumism, thus fring the cover when passing through the groove of the buckle l7 and holding the end or the strap through th hole 20, by means of the rings in the mechanism, such as described heretofore, such closinp once shut not being separable, except by destruction of the handle on the same, thereby obtaining an absolutely sai'e seal.

l laving thus described my invention, what claim as my invention and I therefore dosire to protect by patent is the following:

1. In a safety seal, a container having slots therein and an open side,a cover carried by the container and adapted to be folded over the open side of the latter, strap carried by the cover and having a slot therein adaptec, wh n the cover is closed and the strap is passed through one of the slots in the con tainer, to register ith the other slot in the container to permit the insertion oi the free end of the strap through said registering slots whereby to lock the cover in closed position, and means arranged within the container and coacting with the extremity of the trap for fastening the latter in place.
